There's always enough blame to go around when a team loses, especially by an embarrassing score of 50-17, but the Buffalo Bills defense had shirked blame for the team's shortcomings over the past few weeks.

Today's performance revived those concerns.

The Bills defense had improved so dramatically over the past four weeks, especially against the run, but it got ugly early when Buffalo allowed 30 yards on five carries on Seattle's first drive, which was capped off by a 14-yard touchdown run by quarterback Russell Wilson.

It didn't get much better from there. As a team, the Seahawks averaged 8.4 yards per carry against Buffalo. Wilson finished with 92 yards on nine carries and three touchdowns. Running back Marshawn Lynch had 10 carries for 113 yards and a touchdown of his own.

Sure, a bad day from quarterback Ryan Fitzpatrick didn't help, but the Bills were already down 14-0 by the time they got the ball for the second time, just 9:21 into the first quarter, and gave up 31 points after the Seahawks scored on all of their first five drives.

It looks like the Bills defense has regressed to its previous mean, but it's also entirely possible that the Bills just ran into a red hot opponent—the Seahawks have now scored 108 points in their past two games, and had averaged 5.5 yards per rush attempt over the three games headed into this one.

But while a lot has made of the coaching staff and the quarterback in recent weeks, the defense has been in the headlines for the wrong reasons almost all season (save their recent hot streak) and this recent performance didn't bode well for Buffalo's defensive line.

The Bills must be wondering whether their defensive personnel is a fit in the scheme.

The return of defensive end Mark Anderson meant nothing. (Did he even play?) The Fox Sports cameras caught defensive tackle Kyle Williams barking at defensive end Mario Williams at one point early in the second quarter, and while the nature of the conversation is unknown, the timing (immediately following Wilson's second touchdown run) suggests they weren't making plans to have a tea party following the game.

Defensive end Kyle Moore looked lost in run defense as well, losing containment on a pair of big runs to the outside.

They must also be wondering whether defensive coordinator Dave Wannstedt's scheme is designed for success. The Bills often send their defensive linemen on straight rushes, and the predictability makes them easier to block.

In a performance where everything went so wrong, it's hard to tell at this point.
